The Beijing Olympic Games, aspiring toward “One World, One Dream,” were intended to elicit feelings of international unity. As such, once reminded of the Beijing Games, people should perceive fewer differences between cultures. Alternatively, given its competitive nature, the Beijing Games may lead people to contrast cultures and see heightened intergroup differences. Findings supported the latter process. After being primed with the Beijing Olympic icon, Chinese and American participants high in nationalism and patriotism perceived greater differences between Chinese and American cultures, compared to those low in nationalism and patriotism. Among Chinese participants who believe society is malleable, exposure to the icon increased perceived cultural differences, compared with those unexposed to the icon. Chinese participants who believe society is fixed saw similarly high levels of differentiation between the cultures, whether or not they were exposed to the icon. Implications for Sino-American relations and globalization are discussed.
